SustainableHNL (sHNL)

SustainableHNL (sHNL) is the first airport sustainability initiative and pilot for the Hawaii Department of Transportation—Airport’s Division, SustainableDOT-A's (sDOT-A) airport system sustainability program. SustainableHNL (sHNL), was launched through the leadership of the sHNL Committee—a dynamic, interdisciplinary, and consensus-based team of DOT-A and Oahu District stakeholders inspired by the vision of Hawai'i airports as leaders in sustainability. The sHNL Committee began working together with the understanding that HNL protocols would be replicated, yet uniquely implemented across Hawaii’s airport system. To date, the sHNL Committee has engaged stakeholders, conducted assessment, published the SustainableHNL- Elements Baseline report, the Elements Baseline Update report, and the Sustainable Management Plan.

 

 

SustainableHNL Committee (sHNL Committee)

The sHNL Committee was created to make executive decisions to sustain HNL’s goals as described in the HNL Sustainability Policy. The sHNL Committee is comprised of individuals that stem from the ACI-NA’s EONS model. The sHNL Committee is able to assess projects and programs as a holistic body and conclude decisions that will most benefit the airport. The role of the sHNL Committee is to:

    • Develop and Foster a Sustainable Culture
    • Lead Sustainable Initiatives
    • Educate Others of Sustainable Practices
    • Monitor Progress of Sustainable Developments
    • Analyze Life Cycle Operating Costs
    • Participate in Sustainability Partnerships 

 

sHNL Sustainability Policy

The HNL Sustainability Policy supports the DOT-A’s goals to actively pursue opportunities for airport sustainability at HNL.

HNL Sustainable Management Plan


The HNL Sustainable Management Plan (SMP) has been developed to support Sustainable HNL and its ongoing mission to incorporate the principles of sustainability in all aspects of airport operations. Built upon the 2009 sHNL-Elements Baseline and 2014 Baseline Update, this SMP provides the framework for a management plan rooted in the best practices of sustainability. The goal of the SMP is to optimize airport operations while reducing environmental impacts, realizing economic benefits, and improving community relations. Through the SMP, HNL will align with the State and local goals, policies, and initiatives by conducting a comprehensive analysis of how and where sustainability management is implemented into long-term planning.

Energy Savings Project HNL

 

HNL is a shining example of how the DOT-A is working toward the Hawaii State goal of 100% clean energy by 2045.

 

Project Size
• 5,596,869 sq. ft. of buildings


Expected Energy Savings
• 40% average annual energy savings (38,603,887 kWh)

 

Expected Annual Utility Cost Savings (Electricity and Water)
• $10.9 million first year savings

 

Expected Annual Carbon Emissions Reduction
• 27,601 metric tons of CO2

 Over 2,400 solar photovoltaic panels are installed on the Central Concourse.  Solar PV offset 11% of HNL's energy demands in the first year.

 

Airport Carbon Accreditation

Between 2009 and 2014, HNL reduced its carbon emissions per passenger by 11%, achieving a Level 2 Reduction accreditation from third party Airport Carbon Accreditation and recognition by Airports Council International – North America (ACA website). Launched by Airports Council International - Europe, the Airport Carbon Accreditation program has a goal of carbon neutrality at airports across the globe. HNL was one of the first 10 airports in North America to become accredited (ACI NA press release). Fact sheet

FOD Walk

HNL’s FOD Walk program is a recurring volunteer event to address the issue of Foreign Object Debris / Foreign Object Damage (FOD), which threatens the safety of aircraft, airport vehicles, equipment, and passengers. It brings together the airport community to clean up the airport and build awareness.

Recycle Drive

HNL’s biannual Recycle Drive invites tenants to bring in their infrequent waste items, such as e-waste and bulky items, to be properly recycled, reused, or responsibly disposed.

LEED Projects

The Hawaii Airports Modernization Program is pursuing LEED or equivalent certification for the following projects. More info can be found here: http://www.hawaiiairportsmodernization.com/

 

    • HNL TMP New Mauka Concourse Improvements
    • HNL Consolidated Rental Car Facility

 

Due to the nature and variety of airport project types and with LEED being only applicable to occupied buildings, further initiatives were taken by the DOT-A to ensure sustainable initiatives were implemented in all projects. The Sustainable High Performance Guidelines (SHPG) was developed to provide a process to facilitate the integration and implementation of sustainable best practices in all developing projects.

 

Sustainability Projects

The DOT-A has taken proactive measures to develop sustainable practices that are in line with the State and the aviation industry, including the following:

 

  • Energy savings project to implement and manage energy conservation measures (ECMs) backed by an energy savings performance guarantee. The projected annual savings is $10.8 million dollars from the estimated 38.5 million kWh saved:
    • Lighting – Interior and exterior
    • Air conditioning system upgrades
    • Chilled water cooling system upgrades
    • Air-cooled equipment upgrades
    • Transformer replacements
    • Retro-commissioning of air conditioning and ventilation systems
    • Solar photovoltaic energy generation systems
  •  Participated in HECO’s Green Lights project since its inception, converted T-12 fluorescent lights with T-8 fluorescent lights with electronic ballasts.
  • Upgraded the airfield taxiway light fixtures and guidance signs with LED technology in 2007. HNL was able to achieve a reduction in energy consumption of nearly 600,000 kWh per year.
  • Installed a chilled water loop and replaced a/c chiller plants. The chilled water loop was completed in 2009; the Diamond Head chiller plant was completed in 2009. HNL will reduce their energy usage by 3,850 MWh annually.
  • Replaced light fixtures in the Interisland Parking Structure with fluorescent fixtures. The existing fixtures used 175 watts each while the fluorescent fixtures uses 85 watts and have a five times greater life expectancy.
  • Added remote control and data acquisition devices (Supervisory Control and Data Acquisition or SCADA) to electrical switches to allow the Energy Monitoring and Control Systems (EMCS) to better control electrical use for energy conservation.
  • HNL’s irrigation is tied into non-portable water from Sumida Watercress Farm. 
  • Evaluating the use of LED lights in certain areas of the airport.
  • Replacing existing 400 Hz converters with more energy efficient converters. These provide power for aircraft at the gates to run their air conditioning and other electrical needs. Otherwise, the these aircraft would have to run their on-board Auxiliary Power Units (APUs) which would use the on-board fuel and less efficient air pollution control devices.
  • Testing on-site wind energy potential by installing a 16 kw array of small wind energy generators at the new airfield vault and maintaining cost data. image 1 image 2
